SmartGuardAnti Snore Device. New Customizable Snore Reducing Mouthpiece – Reduce Snoring Aid for Men and Women – Most Comfortable and Adjustable Oral Appliance - Holds Jaw Forward to Open Airway

I first tried a more expensive ($120) adjustable mandibular advancement device (MAD), one not sold on Amazon. As soon as I put it into my mouth, it became clear that there would be severe problems with my use of it. Thus I searched Amazon for a device that addressed those problems. I found the SmartGuard and I have used it for just over a month. I am extremely happy with it and I expect to gladly replace it several times a year. I hope that it remains available! I offer these comments in the hope that they will help someone else choose an effective MAD for themselves.In my opinion, the SmartGuard has a unique set of features that address many of the problems with other MADs.First, it is assembled by the user from two separate pieces, a top tray and a bottom tray. The retainers for the upper and lower teeth are thus molded to your teeth separately, so that each can fit the teeth more precisely. This system actually works, especially for those of us with an overbite. I find that the resulting fit to my teeth is very secure. On the other hand, devices which require the upper and lower to be molded at the same time require you to align your teeth vertically during the molding process. For those of us with an overbite, this means you are molding while attempting to hold your jaw in a very unnatural position, making it difficult to get a good mold.Additionally, because there are two separate pieces, the whole assembly can be kept relatively small. In other words, it does not fill your mouth, and that fact allows you to keep your mouth closed while sleeping. Yet you can also open your mouth when needed. These were important criteria in my search.The separation of the upper and lower trays also allows the adjustment of the size of the arch of the upper tray to better fit your teeth. This was not one of my criteria, but it seems like it could help some people.Secondly, it is adjustable for the relative position of the lower jaw with respect to the upper teeth. In the SmartGuard, this adjustment was designed while keeping people with overbite in mind -- that is, the device can be set up with the lower piece not as far forward as the upper piece. This was the most important criterion for my particular search, as I do have an overbite, and where the furthest back position of the first device I tried forced my jaw into a very uncomfortable, too far forward, position.There are some things to be aware of about the SmartGuard:Because the upper and lower trays are molded to your teeth separately, it is important to pay attention to the alignment of each tray to your teeth. The trays each have an alignment notch that is meant to be centered on the middle of your teeth during molding. I suspect that some of the people who have found this device to be uncomfortable have not correctly aligned the trays with their teeth during molding. I know that happened to me the first time I molded it. If the alignment between upper and lower trays is not correct, the device cannot be expected to work properly.It is important to make sure that the soft parts of the upper and lower trays do not contact each other during the molding process. If they do, they will stick together. This is not mentioned in the instructions.While it is easy to assemble the device, it tends to be difficult to disassemble it to change the length of the bars. The instructions advise removing the bars from the lower tray first, and I have found that to be good advice.Update after nearly one year of use:The first unit that I used eventually failed by the soft portion of one of the trays separating from the hard portion. I had already prepared a second unit, and the transition to the second unit was problem free. However, when I prepared a third unit, I ran into a problem -- it did not fit well at all. I then prepared a fourth unit, and that one fit better than the third one, but it was not as comfortable as the first two.I closely examined all of the last three units for physical differences that could explain the comfort results. I did not find anything other than the fact that the fitting process leads to different results on different attempts (at least for me). In fact, I was able to increase the comfort level of the third unit a lot by repeating the fitting process on it.It seems clear to me that the amount of physical jaw advancement will generally differ between units that are assembled with the same numbered adjustment bars; depending on how the fitting process goes. I may get better at getting repeatable fitting results as time goes on, but as it is, I think I am getting about the same advancement with setting 3 on the fourth unit as I am with setting 4 on the second unit. This matters to me because this device is extremely effective at reducing the specific type of sleep apnea that I have, given the appropriate level of jaw advancement, as shown by multiple home sleep studies.I did also find that the manufacturer had increased the thickness of the adjustment bars for the later units -- this was not obvious by eye, but was easily discovered when I tried to interchange the adjustment bars between units.

First of all, let me say this device is awesome. I wish I were being paid or given free replacements in exchange, but unfortunately, I'm paying for it myself. I've been on a quest to end my chronic snoring. I've been convinced I've had sleep apnea for years, but I've taken a sleep lab test and home study tests and have never been diagnosed. I've lost weight and am currently very thin. I decided to really start exploring mouthpieces. I started with SnoreRX, which was an okay device, but I found it hard to keep in at night, and it didn't eliminate snoring; plus, it dried out my lips terribly. Next, I tried Difiniy, which did not really help with snoring at all. The fit isn’t tight enough, plus it’s really hard to close your mouth around, and it fell out every single night for nearly 30 nights. I was about to give up my efforts, but I decided to buy this SmartGuard product. When I first got it, opening the box felt a little overwhelming. If you've used other mouthguards, this one has a lot of pieces in the box, and the mold for the mouthguard looks different. However, I watched their YouTube video, and it was pretty straightforward. But I can quickly give the steps.1. Boil water, preferably in the microwave, and you'll need a good bit, like 2 cups (about 5 minutes or so).2. While the water is in the microwave, place the upper mouthguard on the tray; this will help you adjust it to your arch.3. When the water finishes boiling, put the mouthpiece (both top and bottom) in the water and start a timer for 1 minute.4. Take a quick drink of cold water, swishing it around your mouth.5. Pull out the upper mouthguard with the tray, let it drip for a few seconds, and place it in your mouth, using the tray to adjust it to your arch. Once you have it positioned, bite down and suck while pressing your tongue against the inner portion of the mouthguard.6. After about 30 seconds, pull out the bottom mouthguard (the top is still in your mouth) and place it in.7. Do the same steps as 5, except without the tray. Align it to your arch, then bite down and suck while pressing your tongue against the inner part.8. Set a timer for 2 minutes and keep sucking and pressing your tongue against the mouthguard, ensuring it's tight against the teeth; it's important for retention.9. After the timer runs out, remove the mouthguard and toss it into some cool water.10. Place the correct spacer on the guard. I have a nearly one-tooth overbite, but I had to start with the #1 setting, even though they recommend a #2 for starting. I have worked my way up to the #2 now.I will say that with the spacers attached, it does seem a little delicate to handle; however, it's pretty easy to pop them back in. Also, it isn't an issue when it's in your mouth.The first night I wore this device, I managed to keep it in all night, plus I didn't wake up at all. It really holds your jaw firmly forward and even makes your face look a little distorted (my iPhone sometimes won't recognize my face when I have it in). I typically follow my evening water flosser, mouthwash, and brushing routine and then put in the mouthpiece about 30 minutes before bed. You can sleep with your mouth open or shut (although shut is challenging the larger the spacer you use). However, I have kept this in every single night and slept until my alarm goes off without fail since the first time (granted, I was already used to wearing a mouthpiece from other companies for some time before trying this one). I can say that I've been told I no longer snore at all; in fact, with the mouthguard in place, I can't even make a snoring sound. Perhaps that should be a check for whether you have it spaced correctly or not, I do not know.Next comes the hygiene portion of this. This is a temporary device, but it's $70, and you want it to last. The little travel case you get with it doubles as a cleaning reservoir. I bought their cleaning product, which is pretty cheap. There is a small water fill line; I used hot water initially to help the solution dissolve. You fill it up to the line, pour in the powder, and let it dissolve. You may need to stir, then drop in your mouthguard and fill it with water until the mouthguard is completely submerged. I just leave mine in there all day (which it says you can do) and pull it out after I complete my evening teeth routine, rinse it off, and place it in a separate case from one of the other, ineffective mouthguards I had until I'm ready to wear it.Pros:- Stopped my snoring- Fits tightlyCons:- A little delicate to handle when not in your mouth- Can leave your teeth and/or jaw a little sore in the morning, but it goes away after a few hours, and I'll gladly trade a sound-free, restful night’s sleep for a little soreness in the morning.Overall: This is a buy; try it out. I'm certain the company will honor their warranty for a refund if it doesn't work for you, so there’s really nothing to risk here if snoring is an acoustical problem in your household or if you just aren't getting enough sleep.Again, I'm not being paid or compensated in any way, although I'd love a couple of free mouthguards to ensure that I remain snore-free for years to come!
